NOTE: The MAC MASTER KEY feature is applicable only to ter-
minals using Triton Standard ATM software and a Secure Pin Entry
Device (SPED) module.
IMPORTANT: The MAC MASTER KEY must be entered before the
MAC Working key.
MAC is an acronym for Message Authentication Code. The MAC
MASTER KEY is used to protect the MAC WORKING KEY during
manual entry or downloading of the working key. The MAC MAS-
TER KEY is a 16-character string, consisting of the digits 0-9 and
the letters A-F. Your processor must provide you with the MAC
MASTER KEY. If a MAC authentication attempt on a message fails,
the message will fail. This is a security precaution.
For security reasons, when entering this key, a ‘*’ is displayed in
place of the actual character. Since it is not possible to view the
key while it is entered, the key must entered in twice to make sure
it was entered properly.
To enter a digit 0-9, simply press the key that has that digit, and a
‘*’ will appear. To enter the letters A-F, first press the key,
then press the key that has the letter you want on it. The first press
of the key will display the first character above the number. Sub-
sequent presses will display the characters in sequence. When
the character you want is displayed, press the
key to ‘lock in’ the letter. If your next character is a letter, you must
press the key again. Press the key to clear
the entry and start over. Press the key to back
up and erase a character.
In some versions of ATM software the
MAC MASTER KEY consists of TWO
16-character strings: a LEFT KEY
BLOCK and a RIGHT KEY BLOCK:
Each block consists of some combi-
nation of the digits 0-9 and the Hexa-
decimal (“Hex”) characters A-F. Fol-
low these instructions if your ATM
uses LEFT and RIGHT KEY
BLOCKS.
Selecting the LEFT KEY BLOCK or
RIGHT KEY BLOCK option will dis-
play the appropriate key-entry screen,
